Description

Technical Field

[0001] This utility model relates to the field of rescue equipment technology, and in particular to a foldable rescue device. Background Technology

[0002] A life ring is a buoyancy rescue device. Its core principle is to use low-density materials (such as polystyrene and foam plastic) or a closed air cavity to generate buoyancy greater than the weight of the human body, so that the person who falls into the water can float face up.

[0003] However, current lifebuoys have the following problems: the air inside makes them heavy and difficult to throw; their small size makes them inconvenient to grab when rescuing people in the water and they cannot be used by multiple people at the same time. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing lifebuoys being too heavy to throw and inconvenient to grab during use, and to propose a foldable rescue device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a foldable rescue device, comprising a chassis, a bottom cover, a top chassis, a top cover, and an airbag. The corners of the outer surfaces of the top chassis and the top cover are connected by bolts, and the corners of the outer surfaces of the chassis and the bottom cover are also connected by bolts. A housing and several threaded cylinders are fixedly connected to the top of the chassis. A compressed gas cylinder filled with compressed nitrogen is installed inside the housing. Two gas supply pipes are fixedly connected to one side of the compressed gas cylinder. The end of the gas supply pipe away from the compressed gas cylinder is fixedly connected to one side of the airbag. A solenoid valve is installed on the outside of the gas supply pipe. The gas supply pipe is equipped with a spherical valve body inside, and a through hole is opened on the outer surface of the valve body. The operation of the solenoid valve can control the rotation of the valve body. Several screws are slidably inserted into the inner wall of the top plate, and the outer surface of the screws is threadedly connected to the inner wall of the threaded cylinder. A screw cap is threadedly connected to the top of the inner wall of the compressed gas cylinder. A power block is provided at the top of the inner wall of the top cover. A control button is provided at the top of the outer surface of the top cover. An ultrasonic sensor is provided at the bottom of the outer surface of the bottom cover. A strap is fixedly connected to one side of the air bag, and a conical locking block is fixedly connected to the end of the strap away from the air bag. A buckle is inserted into one side of the chassis.

[0006] Furthermore, the outer surface of the airbag is provided with several auxiliary straps, and the two ends of the auxiliary straps are fixedly connected to the outer surface of the airbag by adhesive bonding.

[0007] Furthermore, a protective frame is fixedly connected to the bottom end of the bottom cover, and the protective frame is hollow.

[0008] Furthermore, wiring holes are provided on the outer surfaces of the housing, chassis, and top plate.

[0009] Furthermore, a sleeve is fixedly connected to the bottom end of the top plate, and the inner diameter of the sleeve is adapted to the diameter of the threaded cylinder.

[0022] Example 1, as Figure 1-8As shown, a foldable rescue device includes a chassis 1, a bottom cover 13, a top plate 7, a top cover 10, and an airbag 5. The corners of the outer surfaces of the top plate 7 and the top cover 10 are connected by bolts, and the corners of the outer surfaces of the chassis 1 and the bottom cover 13 are also connected by bolts. A housing 2 and several threaded cylinders 3 are fixedly connected to the top of the chassis 1. A compressed gas cylinder 4 filled with compressed nitrogen is installed inside the housing 2. Two gas supply pipes 41 are fixedly connected to one side of the compressed gas cylinder 4. The end of the gas supply pipe 41 away from the compressed gas cylinder 4 is fixedly connected to one side of the airbag 5. A solenoid valve 42 is installed on the outside of the gas supply pipe 41, and a ball valve body 43 is installed inside the gas supply pipe 41. A through hole is opened on the outer surface of the valve body 43. The operation of the solenoid valve 42 can control the rotation of the valve body 43. Several screws 8 are slidably inserted into the inner wall of the top plate 7. The outer surface of the screws 8 is threadedly connected to the inner wall of the threaded cylinder 3. A screw cap 9 is threadedly connected to the top of the inner wall of the compressed gas cylinder 4. A power block 12 is provided at the top of the inner wall of the top cover 10. A control button 11 is provided at the top of the outer surface of the top cover 10. An ultrasonic sensor 14 is provided at the bottom of the outer surface of the bottom cover 13. A strap 17 is fixedly connected to one side of the airbag 5. A conical locking block 18 is fixedly connected to the end of the strap 17 away from the airbag 5. A buckle 16 is inserted into one side of the base plate 1. In the normal state of the rescue equipment, the strap 17 is wrapped around the outside of the airbag 5 located between the base plate 1 and the top plate 7. Inserting the locking block 18 at one end of the strap 17 into the buckle 16 can fix the position of the airbag 5. When using the rescue equipment, press the top cover. The control button 11 at the top controls the power supply, energizing the control panel inside the power supply and powering the ultrasonic sensor 14 located at the bottom of the base cover 13. The entire device is then thrown towards the person being rescued. During the throw, due to the weight of the chassis 1, the ultrasonic sensor 14 at the bottom of the base cover 13 faces downwards. Simultaneously, the ultrasonic sensor 14 emits ultrasonic pulses towards the water surface. The pulses are reflected by the water surface, and the ultrasonic sensor 14 receives the echo signal. Based on the formula (distance = speed of sound × Δt / 2), the distance between the device and the water surface is calculated in real time. When the distance is one meter, the control panel controls the operation of the solenoid valve 42 on the outside of the air supply pipe 41. The solenoid valve 42 controls the rotation of the valve body 43, causing the through hole on the outer surface of the valve body 43 to connect with the air supply pipe 41. With the direction aligned, the compressed nitrogen inside the compressed gas cylinder 4 will quickly fill the airbag 5 through the gas supply pipe 41, causing the airbag 5 to inflate rapidly as it falls near the water surface. As the airbag 5 inflates, the locking block 18 will pop out from inside the buckle 16, and the airbag 5 will then unfold in a hexagonal grid pattern and land on the water surface. Personnel can hold onto the outer surface of the airbag 5 to be supported on the water surface for rescue. When retrieving the equipment after use, the two solenoid valves 42 on the outside of the compressed gas cylinder 4 are controlled by the control button 11 to close the valve body 43. The bolts connecting the top cover 10 to the top plate 7 are removed from the outer surface of the top cover 10, and the top cover 10 is opened. Then, each screw 8 on the outer surface of the top plate 7 is rotated to disengage from the threaded cylinder 3, allowing the top plate 7 to be removed.Next, rotate the screw cap 9 to remove it from the top of the compressed gas cylinder 4. Fill the compressed gas cylinder 4 with compressed nitrogen using the inflation device. Then, insert the screw cap 9 back into the top of the compressed gas cylinder 4 and rotate it to seal the top of the compressed gas cylinder 4. Next, vertically clamp the top plate 7 downwards onto the top of the housing 2. Use several screws 8 to pass through the top plate 7 and insert them into the threaded cylinder 3. Rotate the screws 8 to screw them into the threaded cylinder 3 to connect the top plate 7 to the base plate 1. Then, attach the top cover 10 to the top of the top plate 7 and use bolts to secure the top cover 10 to the top plate 7. Connect the airbag 5 by pulling the strap 17 on one side to wrap it around the outside of the shell 2 and the threaded cylinder 3. After wrapping it once, insert the locking block 18 at one end of the strap 17 into the buckle 16 to return the device to its initial state. Through the split structure, compressed gas is filled into the compressed gas cylinder 4, keeping the airbag 5 in an uninflated state under normal conditions. Compared to traditional lifebuoys, it is lighter. The improved throwing method increases the throwing distance. When in use, the airbag 5 inflates in a grid pattern, increasing the rescueable area and improving the rescue success rate.

[0023] Reference Figure 2-8 As shown in this embodiment: the outer surface of the airbag 5 is provided with several auxiliary straps 6. The two ends of the auxiliary straps 6 are fixedly connected to the outer surface of the airbag 5 by adhesive. After the equipment is deployed on the water surface, personnel can hook onto the auxiliary straps 6 on the outer surface of the airbag 5 and pull the airbag 5 and the equipment as a whole to move, making it easier to grab the airbag 5.

[0024] Reference Figure 2-8 As shown in this embodiment: a protective frame 15 is fixedly connected to the bottom end of the bottom cover 13. The protective frame 15 is hollow. By setting the hollow protective frame 15, the bottom outer side of the ultrasonic sensor 14 can be protected, so as to avoid the ultrasonic sensor 14 being directly impacted by the water surface when the equipment is submerged in water, thus protecting the ultrasonic sensor 14.

[0025] Reference Figure 2-8 As shown in this embodiment: wire holes 19 are provided on the outer surfaces of the housing 2, chassis 1 and top plate 7. The lines connecting the ultrasonic sensor 14 inside the chassis 1 and the solenoid valve 42 inside the housing 2 to the power supply can be threaded through the wire holes 19.

[0026] Reference Figure 2-8As shown in this embodiment: a sleeve 20 is fixedly connected to the bottom end of the top plate 7. The inner diameter of the sleeve 20 is adapted to the diameter of the threaded cylinder 3. When installing the top plate 7, after the top plate 7 is placed on the outer side of the top of the housing 2, the sleeve 20 at the bottom end of the top plate 7 is placed on the top end of the threaded cylinder 3, which can limit the angle between the top plate 7 and the threaded cylinder 3, making it convenient to connect the screw 8 to the threaded cylinder 3. A positioning ring 21 is fixedly connected to the bottom end of the top plate 7. The positioning ring 21 is located inside several sleeves 20 on the bottom surface of the top plate 7. When the airbag 5 is deployed between the base plate 1 and the top plate 7, the positioning ring 21 and the threaded cylinder 3 can restrict the shape of the outer surface of the airbag 5 and the deployment position, so that the compressed nitrogen can diffuse and deploy more evenly inside the airbag 5.

[0027] Working principle: When using the rescue equipment, press the control button 11 at the top of the top cover 10 to power on the control panel inside the power supply, which in turn powers the ultrasonic sensor 14 located at the bottom of the bottom cover 13. Then, throw the entire equipment towards the person being rescued. During the throwing process, due to the large weight of the chassis 1, the ultrasonic sensor 14 at the bottom of the bottom cover 13 faces downwards as the equipment flies. Simultaneously, the ultrasonic sensor 14 emits ultrasonic pulses towards the water surface. The pulses are reflected by the water surface, and the ultrasonic sensor 14 receives the echo signal. Based on the formula (distance = speed of sound × Δt / 2), the distance is calculated in real time. The distance between the calculated device and the water surface is determined. When the distance is one meter, the solenoid valve 42 on the outside of the air supply pipe 41 is operated via the control panel. The solenoid valve 42 controls the valve body 43 to rotate, aligning the through hole on the outer surface of the valve body 43 with the direction of the air supply pipe 41. At this time, the compressed nitrogen inside the compressed gas cylinder 4 will be rapidly injected into the airbag 5 through the air supply pipe 41, causing the airbag 5 to inflate rapidly as it approaches the water surface. When the airbag 5 inflates, the locking block 18 will pop out from inside the buckle 16. Subsequently, the airbag 5 unfolds in a hexagonal grid pattern and lands on the water surface. Personnel can hold onto the outside of the airbag 5. The airbag 5 is used to hold personnel on the water surface for rescue. When the equipment is recovered after use, the two solenoid valves 42 on the outside of the compressed gas cylinder 4 are controlled by the control button 11 to close the valve body 43. The bolts connecting the top cover 10 to the top plate 7 are removed from the outer surface of the top cover 10, and the top cover 10 is opened. Then, each screw 8 on the outer surface of the top plate 7 is rotated to disengage the screw 8 from the inside of the threaded cylinder 3, and the top plate 7 is removed. Then, the screw cap 9 is rotated to remove the screw cap 9 from the top of the compressed gas cylinder 4. Compressed nitrogen is then filled into the compressed gas cylinder 4 through the inflation device. Finally, the screw cap 9 is inserted back into the cylinder. Turn the screw cap 9 at the top of the compressed gas cylinder 4 to seal the top of the compressed gas cylinder 4. Then, vertically clamp the top plate 7 downwards onto the top of the housing 2. Use several screws 8 to pass through the top plate 7 and insert them into the threaded cylinder 3. Turn the screws 8 to screw them into the threaded cylinder 3 to connect the top plate 7 to the base plate 1. Then, attach the top cover 10 to the top of the top plate 7 and use bolts to connect the top cover 10 to the top plate 7. Pull the strap 17 on one side of the air bag 5 to wrap the air bag 5 around the outside of the housing 2 and the threaded cylinder 3. After wrapping it once, insert the locking block 18 at one end of the strap 17 into the buckle 16 to return the equipment to its initial state.
